A short buying guide on portable fish finders
Unless you own the best portable fish finder 2017, you will end up circling the lake in your boat and not catching any fish that will can give you a satisfied feeling on a job well done. You can’t possibly imagine yourself going around the whole lake unguided without knowing which spot yields the greatest catch. These elements make a fish finder a good investment to make.
Transducers, which are the main units in your fish finder, can be dual frequency types. This means they come with both 60 and 20 degree cones. Frequency is a huge element when it comes to fish finders. Majority of models offer from 50, 83, 192 or 200 kHz frequencies, which are all determined by the unit’s cone angle.
For shallow water, you will want high frequencies such as 192 and 200 kHz. For deep water, you would prefer something that goes at a low 50 kHz. With a higher frequency, you will naturally see greater detail on the screen. This is thanks to the greater number of sonar waves that are sent out by and sent back to the transducer. Some models are even able to deliver 400 or greater kHz accompanied with multiple frequencies, which ensure greater image detail and also enable you to switch frequencies so you can get a broader and more general view as well as narrower views with more detail.
An extremely crucial aspect you will have to consider when checking out products in portable fish finder reviews is power. Power is measured in wattage rating. The higher the wattage, the more able the device is at displaying images faster while also ensuring deeper readings. With lower wattage ratings, the device will be slower and more suitable for use in shallow water. The sonar waves are translated by the device as they are received from the transducer. With lower power, you get slower transmission of sonar waves, which can also bring about a fuzzy reading. Waves are transmitted faster when the device has greater power, resulting in clearer readings. Keep in mind that in shallow water, you will need less power in your fish finder. For fishing in deep water, you will want greater power.
Screen Resolution and Type
When checking out fish finders, you will want to look into the amount of pixels a unit provides. The greater number of pixels there is, the greater detail you will see. Thus, if the device has 640 pixels vertically and 640 pixels horizontally, you will see a greater amount of detail compared to a minimum resolution of 240 vertical x 160 horizontal pixels. That minimum resolution will give you blocky images at the most so you may opt for a unit with higher resolution.
Color screens also deliver more detail since you basically see a lot more color compared to only 256 grayscale shades. With a color screen, you see fish and underwater objects in detail while enabling easy viewing in bright light compared to plain black and white screens. Black and white units are budget friendly, though, and are a good starting point. .
Perfect for angling, kayak fishing, boat fishing and ice fishing, the Deeper DP0H10S10-P is a wireless fish finder equipped with a smart wireless sonar to go well with your tablet or smartphone. The sonar employs Bluetooth technology for transfer of sonar readings to the device from as deep as 150 feet. The device needs no cellular data to make the sonar operate, thus enabling use anywhere. A wide area is covered for sufficient search capability while a narrow search area is also available to derive high accuracy returns. Weighing in at just 0.22 pound, this is a superbly small and light device compared to traditional flashers or sonars.
Compact and easy to use, the device needs no complicated installation, wiring or external batteries for successful setup. The awesome tennis ball size lets you fish anytime of the year anywhere. Compatible with the iOS5+ and Android 2.3 smartphone and tablet models, this device comes with an all-in-one application that provides the latest features plus unique content including an integrated camera function, a lunar calendar, updated weather reports, an integrated map function and much more.
Equipped with plenty of features to make every fishing trip truly rewarding and worth taking, the Lowrance 000-11673-001 Elite-3X provides effortless viewing of what is beneath your boat. It offers wide angle views even in full sunlight due to the fantastic capability of its 320 x 240 resolution delivered via the LED-backlit color display. See bottom hardness, thermoclines, fish targets, bottom contours, structure details and more delivered with awesome clarity using the Broadband Sounder™ detail of the fish finder.
Get maximum view beneath your boat by leveraging the dual-frequency operation of the unit. For 60 degrees of conical coverage that enables large area searching and display of large fish arches, optimize the 83 kHz frequency. To make the most of 20 degrees conical coverage, switch to the 200 kHz frequency. This lets you enjoy better lure tracking as well as fish target separation. The Fish ID feature displays fish icons so you won’t have to rely on just fish arches for identifying fish targets. The Pages button lets you do quick switching between 83 kHz and 200 kHz sonar frequency views.
The Signstek FF-002 is a reliable handheld fish finder developed for both amateur and professional anglers. Employing sonar sensor, the device helps users find the location of fish. Usable in lakes, river or oceans, the device makes the most of sonar technology to locate and define bottom contour, structure depth and composition right underneath the transducer, which then sends a sound wave signal while computing the distance by measuring the time it takes from the transmission of the sound wave to the time for the sound wave to reflect off the object. The reflected signal is then used to verify the size, location and composition of objects.
Because of its wireless design, this device is quite easy to use. Just attach the transducer to the end of the fishing line and toss it into the water like you would a float or fishing lure. Delivering either feet or meter readings depending on your preference, the device delivers fish depth indication and big/ small fish identification. It also gives off an audible fish and depth alarm so you know which spot is the best.
